''Sonic Generations: Friendship is Timeless'' is a {{Crossover}} FanFiction between ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' and ''VideoGame/SonicGenerations'', created by [[http://www.fanfiction.net/u/2025847 GreenSonic21.]] It can be found on Website/FanFictionDotNet [[http://www.fanfiction.net/s/7891955 here]] and on Website/FimfictionDotNet [[http://www.fimfiction.net/story/13892/sonic-generations-friendship-is-timeless here.]]

The events of the intro cutscene of Sonic Generations still occur like in the original: Sonic's friends set up a surprise birthday party for him, Sonic shows up to it, and then the Time Eater shows up shortly afterwards, sending Sonic's friends to different parts of Sonic's history.

However, before that happened, the Mane 6 and some of their friends were having a picnic in Ponyville when the Time Eater also shows up and sends the ponies to different parts of Sonic's history.

Now the ponies must join these strange new creatures from another world and destroy this eminent threat that is threatening both of their worlds. Truths will be revealed, lies will be ripped out, and two worlds' fates and a friendship will hang in the balance.

Like in Sonic Generations, the story is divided into three parts:
# [[UsefulNotes/The16bitEraOfConsoleVideoGames Classic Era]]: Chapters 2-6 ([[VideoGame/SonicTheHedgehog1 Green Hill]], [[VideoGame/SonicTheHedgehog2 Metropolis]], [[VideoGame/Sonic3AndKnuckles Ice Cap]])
# [[UsefulNotes/TheSixthGenerationOfConsoleVideoGames Dreamcast Era]]: Chapters 7-11 ([[VideoGame/SonicAdventure Lost World/Windy Valley]], [[VideoGame/SonicAdventure2 Mission Street]], [[VideoGame/SonicHeroes Frog Forest]])
# [[UsefulNotes/TheSeventhGenerationOfConsoleVideoGames Modern Era]]: Chapters 12-15 ([[VideoGame/SonicTheHedgehog2006 Flame Core]], [[VideoGame/SonicUnleashed Dragon Road]], [[VideoGame/SonicColors Sweet Mountain/Planet Wisp]])

Some time later, a SpinOff story has been released, entitled ''Adventures on the Friendship Express'', explaining exactly what happened during chapters 15 and 16 of the original story. It can be found on Website/FanFictionDotNet [[https://www.fanfiction.net/s/9893193/ here]] and on Website/FimfictionDotNet [[https://www.fimfiction.net/story/149663/adventures-on-the-friendship-express here]]. Stages used so far include:
* ''VideoGame/SonicTheHedgehog2'': DummiedOut Hidden Palace Zone
* ''[[VideoGame/Sonic3AndKnuckles Sonic and Knuckles]]'': Lava Reef Zone, Hidden Palace Zone
* ''VideoGame/Sonic3DBlast'': Flickies' Island
* ''Videogame/SonicCD'': Final Fever
* ''VideoGame/ShadowTheHedgehog'': Central City
* ''VideoGame/SonicAdventure'': Twinkle Park
* ''VideoGame/SonicHeroes'': CasinoPark
!!This FanFic contains examples of the following tropes:
* AdaptationExpansion: Despite the fanfic still taking the same games that Sonic Generations took, it does not take most of the levels. Green Hill is still used, but the levels after that are completely different. Some of the events of the original game are also modified: Tails fights Metal Sonic instead of Sonic himself, Nightmare Moon is the boss of the Classic Era instead of the Death Egg Robot, and the Final Hazard takes Perfect Chaos's place, to name a few examples.
** In addition, even though the story takes mostly elements from the 360/[=PS3=]/PC versions of Sonic Generations, it also uses elements from the UsefulNotes/Nintendo3DS version of the game.
* AlwaysCheckBehindTheChair: One portal was found inside a book. Another one was found under a bed.
* AscendedExtra: [[VideoGame/SonicRushSeries Marine]] plays an important role in chapter 14, despite not being featured at all in the original game. [[VideoGame/SonicColors Orbot and Cubot]] also make an appearance, despite only showing up in a {{flashback}} in the original game.
* AuthorAppeal: Chapter 14 uses ''five different pieces of music'', all from [[http://www.youtube.com/user/KingSpartaX37 Delta Brony.]] [[AwesomeMusic/SonicGenerationsFriendshipIsTimeless They're all in this page, by the way.]]
* BaitAndSwitchBoss[=/=]GiantSpaceFleaFromNowhere: Chapter 10 makes you think that Sonic will be battling [[TheRival Shadow]] like in the original game, but then Queen Chrysalis and her army of changelings show up...
** Shadow having a question mark next to his name in the chapter's title is kind of a hint to this.
* BerserkButton[=/=]BewareTheNiceOnes: Do not make Amy angry. Spike learns this the hard way.
** Also, don't insinuate that Shadow's decision to move on means that he doesn't love Maria any more. [[spoiler: Too bad Shining Armor didn't know when to stop.]]
** For that matter, Luna was also livid after learning from Applejack that Eggman blew up his world's moon in half, to the point that she ordered Shining Armor to arrest him.
* BigBadDuumvirate: Dr. Eggman and [[spoiler: Discord]].
* BroughtDownToNormal: During the Changeling attack on Ponyville, Sonic uses the Chaos Emeralds to disable their ability to change shape. Given Chrysalis' reaction, this is probably permanent.
* CallForward: Chapter 1 of the Adventures on the Friendship Express includes a reference to ''VideoGame/SonicLostWorld'', even though, as far as Sonic canon is concerned, this occurs before that game begins.
* TheCameo: Lyra and Bon-Bon follow the group to Chun-nan in chapter 13 and Lyra freaks out when she sees the humans there.
* CanonDiscontinuity: As season 3 of [=FiM=] was being broadcasted during the creation of the fic, the author's done a great job incorporating its canon into the story. [[spoiler:[[Recap/MyLittlePonyFriendshipIsMagicS3E13MagicalMysteryCure Twilight's still not an alicorn, though]] (she does, however, gain wings in chapter 17).]] The events of [[Recap/MyLittlePonyFriendshipIsMagicS3E11KeepCalmAndFlutterOn "Keep Calm and Flutter On"]] also seem to have never happened (at least, not yet), since Discord is one of the {{Big Bad}}s. According to the bonus chapter "The Doctor and the Chaotician", [[spoiler:the events of this fanfic happen not too long before "Keep Calm and Flutter On".]]
* ContinuityNod: More to the [=FiM=] side than the Sonic side ([[ContinuityNod/SonicGenerations as if the original game didn't already have enough Continuity Nods as it is...]]):
** Derpy says a line quite similar to the one she said in her first appearance in chapter 1.
** The numbers that Tails' radar displays in chapter 3 are the original North American release dates for the first three main Sonic games.
** When battling Nightmare Moon in chapter 6, Applejack uses Twilight like a gatling gun, the same way Pinkie Pie did.
** When battling the changelings in Ponyville in chapter 10, Pinkie Pie once again uses her party cannon.
** When Princess Celestia asks Sonic why the Chaos Emeralds are named as such, Sonic gives a brief summary of the {{backstory}} of ''VideoGame/SonicAdventure''.
** When Tails asks if everypony is familiar with mind control, [[Recap/MyLittlePonyFriendshipIsMagicS2E26ACanterlotWeddingPart2 Twilight glances in her brother's direction before answering that they "kind of are..."]]
** King Sombra's horn, which flew off into the distance after he was destroyed at the end of "[[Recap/MyLittlePonyFriendshipIsMagicS3E2TheCrystalEmpirePart2 The Crystal Empire]]", shows up in chapter 13.
** [[Recap/MyLittlePonyFriendshipIsMagicS2E2TheReturnOfHarmonyPart2 Discord once again drinks a glass of chocolate milk, throwing the milk away.]] Sonic wonders if he puts nitroglycerine in the milk.
** Eggman's TheReasonYouSuckSpeech is full of continuity nods to previous [=FiM=] episodes.
* CrisisCrossover: In much the same way as the original game, just replace Classic Sonic with the ponies.
** Adventures on the Friendship Express has The Alpha and the Omega arc where [[VideoGame/PokemonMysteryDungeon Suicine, Lucario, Pikachu]], [[Franchise/TheLegendofZelda Link]], [[Franchise/SuperMarioBros Yoshi]], Classic Sonic and Classic Tails appear to help the heroes fight off Groudon and Kyogre as their presence is causing more problems.
* DemotedToExtra: Perfect Chaos is the boss of the Dreamcast era in the original game. In this fanfic, Chaos does shows up, but in his Chaos 0 form, to help the heroes in the Changeling battle in chapter 10.
* DramaQueen: Rarity, of course, from the second she turns back to normal. The narration even refers to her as such. (She's the [[ImageSource trope image]] ''and'' the page quote for a good reason.) Even what she says is reminiscent of what she said before:
-->'''Rarity''': What are you talking about? That was utterly terrifying! My beautiful body was completely white! And I was floating around like a ghost! Of all the worst things that could happen, that was the. Worst. POSSIBLE. THING!
* EleventhHourSuperpower: Sonic turns into [[SuperMode Super Sonic]] during the FinalBoss fight, of course, but the Mane 6 also [[http://fav.me/d5c1yv7 gain]] [[http://fav.me/d4rffbx Super]] [[http://fav.me/d5ayw0i forms]] [[http://fav.me/d5bh6mm of]] [[http://fav.me/d5a1hbm their]] [[http://fav.me/d5adywz own]].
** In Adventures on the Friendship Express [[spoiler:Modern Sonic and Classic Sonic turn super together to fend off [[VideoGame/SonicUnleashed Dark Gaia]] at the end of The Alpha and Omega arc.]]
* {{Facepalm}}: Sonic, twice.
** When they save Amy and Spike in Metropolis Zone, Sonic does this after Amy says she thought she would never get to flirt with him again.
** After Rarity's initial DramaQueen moment.
** He even does a step-by-step on how to do it: 1:Raise hand. 2:Open palm. 3: Connect palm to forehead.
* FastballSpecial: Twice during the FinalBattle. First, [[spoiler:after Discord summoned [[VideoGame/SonicUnleashed the Werehog]] from Sonic's own Chaos Energy in the hopes of getting an extra ally, only for the Werehog to have a HeelFaceTurn after it was summoned, Super Sonic used it in this manner to distract Discord.]] Then, [[spoiler:after Discord managed to have a little more success with [[VideoGame/SonicStorybookSeries a Black Knight version of Excalibur Sonic]] that was created from the Shadowbolts being blasted by the Element of Loyalty, after it turned on him because it was loyal to Princess Luna, when Discord pulled a YouHaveOutlivedYourUsefulness and made Black Knight Sonic start to disintegrate, he got a DyingMomentOfAwesome by using his {{BFS}} to pull one of these with Super Sonic, sending him right at the Time Eater so he could retrieve the Element of Magic.]]
* {{Foreshadowing}}: Before Discord reveals himself as one of the {{Big Bad}}s, he has made his presence known at several points in the fanfic. The Author's Notes of chapter 16 should explain everything for you.
* {{Gesundheit}}:
-->'''Applejack''': Ah don't what that is, but Ah don't think Pinkie Pie knows anythin' about no nin… ten… du…\\
'''Espio''': Ninjutsu.\\
'''Rainbow Dash''': Gesundheit.
* GreenHillZone: Unlike in the original game, only the TropeNamer's used.
** Planet Wisp is also used, but is not the main focus of the ''VideoGame/SonicColors'' section like in the original game.
* HammerSpace: Referenced in passing, but also might explain how it works: stick object in quills/tail/mane/what-have-you, and done.
* HeyThatsMyLine:
-->'''Dr. Eggman''': We'll see who has issues after I've taken care of both Sonic and the Spirits of Harmony… FOREVER!\\
'''Pinkie Pie''': HEY! That's my line!
* HubLevel[=/=]HubCity: Ponyville is stuck in the {{White Void|Room}} in this story. AS it progresses, more of it appears and is subsequently restored. Apploosa, Cloudsdale, and the village part of the Chun-Nan/Dragon Road chapters also might qualify. The portal to the FinalBoss is located in Canterlot, with a puzzle like in the games, but using the pedestals from the Gaia Temples in ''Unleashed''.
* InterspeciesRomance: Between a pony (Twilight Sparkle) and a hedgehog (Sonic). Sonic claims they're JustFriends, though -- that, and Princess Cadance saw no signs of love between the two of them.
* IWillShowYouX:
-->'''Shadow''': I won't have to chase you down like the coward you are.\\
'''Queen Chrysalis''': COWARD?! I'll show you who's a coward!
* LampshadeHanging: Pinkie Pie. 'Nuff said
* LetsDuet: Sonic and Twilight sing Music/{{Crush 40}}'s "Live Life" together in chapter 13. Tails and Trixie also sing a couple of lines.
* LetsSplitUpGang: The group does this sometimes when searching for a portal in a specific location.
* LoadsAndLoadsOfCharacters: This story features a ''lot'' of Sonic characters (moreso than the original game) and plenty of ponies, including background ones, get some time in the sun.
* MythologyGag: When battling the Egg Wyvern, Sonic teases Eggman by using his taunt lines from ''VideoGame/SuperSmashBrosBrawl''.
* NiceJobFixingItVillain: The power of the Chaos Emeralds was able to prevent the discording from being successful, and if anything, Discord and Eggman's attempt to destroy it only strengthened the friendship that the Mane 6 have! [[EvilCannotComprehendGood And naturally, they don't understand why that happened!]]
* NoIndoorVoice: Princess Luna, obviously. "'''WHAT DO YOU THINK YOU ARE DOING?!'''"
* OffscreenMomentOfAwesome: During the trip to Canterlot, the train passes through [[VideoGame/SonicStorybookSeries the Arabian Nights and Camelot]] and actually stops for Rainbow Dash, Spitfire, and Soarin to race (and win against) Lightning Dust and the Babylon Rogues.
** WordOfGod assures us that we will get actual chapters of these events, however.
* OverusedRunningGag: Espio has clearly had enough of Vector telling the group to "[[VideoGame/ShadowTheHedgehog find the]] [[MemeticMutation computer room]]" or something similar:
-->'''Tails''': We should be right under the control room.\\
'''Vector''': Right under the computer room?\\
'''Espio''': Vector, if you say that one more time…\\
'''Vector''': What? I'm just asking a question!
* TheOverworld: Ponyville. It's not exactly "neutral", though, as that's where the changeling battle in chapter 13 occurred.
* PaintingTheMedium: There are links to music (well, the [=URLs=] are listed, anyway) at the end of the chapter to be used as events in the story. It's not quite as effective as it is in ''Fanfic/AceCombatTheEquestrianWar'' or ''FanFic/ChaoticHarmony'', though.
** This could have something to do with the story being hosted on Website/FanFictionDotNet, which does not allow links to be placed in stories, while the other stories are hosted on [=FIMFiction.net=], which does.
** The version of the fanfic found on [=FIMFiction.net=] fixes this problem by having the actual links to the songs show up exactly where they are supposed to be played, as opposed to the version of the fanfic found on Website/FanFictionDotNet that simply lists the links at the end of the chapter.
* ParrotExpowhat:
-->'''Sonic''': Who’s Discord? That snake-looking thing up there?\\
'''Twilight''': That’s right, Sonic. Discord is a draconequus.\\
'''Sonic''': A what?
* ThePasswordIsAlwaysSwordfish: This is initially {{subverted|Trope}} in chapter 14, when accessing Eggman's system, which requires a password. Tails suggests "EGGMAN", which doesn't work. This is then {{Double Subver|sion}}ted with the password actually being "PASSWORD".
-->'''Spike''': He must've been going for 'so obvious it's overlooked'.\\
'''Rainbow Dash''': Yeah, I can imagine.
* PlotCoupon: There are 13: the 7 Chaos Emeralds and the 6 Elements of Harmony. One of each even gets TakenForGranite, but like the Pure Hearts in ''VideoGame/SuperPaperMario'', they still work after returning to normal.
* PowerGivesYouWings: [[http://fav.me/d5c1yv7 Twilight's Super form]] has shard wings.
* PunctuatedForEmphasis: "I. SAID. OPEN. THIS. DOOR!"
** Also from chapter 18: "STAY… FOR… THE… PARTY."
* TheReasonYouSuckSpeech: Eggman calls out the rest of the Mane 6 for their refusal to trust Twilight in the past, even managing to [[BreakThemByTalking completely break]] ''Princess Celestia'' by calling her out for treating Twilight as a tool for using the Elements.
--> '''Dr. Eggman''': Stop. Just stop right there, Celestia. You've embarrassed yourself enough. I let you speak because I was willing to give you a chance to prove me wrong about your relationship with Twilight, but you've done nothing but disappoint me! You haven't told me anything I don't already know, and you clearly can't take a bone when it's thrown at you... why do you hardly ever see her on your own time anymore? Why does your faith in her seem to be off and on? Why can't you just be open with her? Because you image is more important than anything you care about?! If you do care about her, Celestia, you have a funny way of showing it... you still think that, despite everything, you and Twilight share something special? [[IronicEcho I believe you had some good words of wisdom for this kind of situation. How did they go again? Oh yes, I remember:]] [[Recap/MyLittlePonyFriendshipIsMagicS2E25ACanterlotWeddingPart1 You have a lot to think about.]]
--> '''Dr. Eggman''': Oh, shut up! Don’t embarrass yourself the way Celestia did! Hang on to whatever dignity you have, you pathetic excuse for an intelligent being! You gave Twilight some minor comfort, yes, but it’s meaningless when you consider that, whenever one of you does something, she’s often there to comfort you and you can’t return the favor! [[Recap/MyLittlePonyFriendshipIsMagicS2E3LessonZero Like the friendship report incident.]] When all was said and done, it was out of sight, out of mind. [[Recap/MyLittlePonyFriendshipIsMagicS2E20ItsAboutTime Just like with the whole time travel loop.]] [[IronicEcho After all, it’s Past Twilight’s problem]], isn’t it, Pinkie Pie? [[Recap/MyLittlePonyFriendshipIsMagicS2E25ACanterlotWeddingPart1 And of course,]] [[Recap/MyLittlePonyFriendshipIsMagicS2E26ACanterlotWeddingPart2 her brother’s wedding.]] You think you can ignore what your decision to not trust Twilight could have led to after it was over and the problem and everything associated with it will go away, just like that? [[ShoutOut Well, get a load of THIS]], ponies: it doesn’t work that way!
** The kicker? He's not even halfway done with his speech at this point. He then rips into Shining Armor, pointing out that as much as Shining wanted to deny it-- [[NotBrainwashed what he said to Twilight the night of the rehearsal was completely his own doing, and had nothing to do with Chrysalis's brainwashing.]]
--> '''Dr. Eggman''': Oh sure, Rarity, stick to that same old attitude of yours! Turn your back when you don’t want to hear something and wait until the last minute to do something about it! It’s the same thing with all of you! Heck, Twilight’s brother did it and everything turned out fine in the end!
--> '''Shining Armor''': What’s that supposed to mean?! My special talent is defending the weak; that’s what my cutie mark represents! I joined the Royal Guard and became Captain to protect those ponies, and I would never turn my back on them or Twilight!
--> '''Dr. Eggman''': Oh no? [[Recap/MyLittlePonyFriendshipIsMagicS2E25ACanterlotWeddingPart1 What about the day you were supposed to be married to Cadance]] [[Recap/MyLittlePonyFriendshipIsMagicS2E26ACanterlotWeddingPart2 and ended up at the altar with the Changeling Queen instead?]] Do you remember what happened that day, pretty boy? How you threw away all the trust you had for your sister just to fulfill what you wanted?
--> '''Shining Armor''': I was under Chrysalis’ spell! I wasn’t in control of what I was doing!
--> '''Dr. Eggman''': Indeed you were, but do you know what that spell actually did to you?
--> '''Shining Armor''': I-It stole my love and brainwashed me to neglect Twilight.
--> '''Dr. Eggman''': Not quite, Shining Armor. Yes, it stole your love and fed Queen Chrysalis, but the only other thing it did to you was make you believe she was Cadance, no matter what she did. [[EvenEvilHasStandards Everything you said to your sister, you said it of your own free will! Her spell had no influence over you in that regard!]]
* TheReveal: In Chapter 16, it is revealed that Discord was posing as Nightmare Moon, the Shadowbolts, and Mephiles the Dark the entire time.
* RhetoricalQuestionBlunder: Rainbow Dash asks a question she doesn't want an answer to; she notices Pinkie Pie is about to answer said question and quickly states she wasn't looking for an answer.
* RoyalsWhoActuallyDoSomething: Princess Celestia and Princess Luna actually do some fighting at several points in the story. Shining Armor also counts, since one of the guards refers to him as a prince and he does take place in the action.
* SequelHook: Tails gives Twilight the Warp Ring the group's been using throughout the whole adventure, claiming that it could serve as a memento of their adventure. Sonic then claims that Twilight's magic could probably "find a way to turn it into a trans-dimensional portal or something."
* SheIsNotMyGirlfriend: When Spike claims Amy is Sonic's girlfriend, Sonic quickly places his hands on his hips, telling him she is not (even though Amy thinks otherwise).
** And when Gilda claims Sonic is Rainbow Dash's boyfriend, Rainbow Dash quickly retaliates.
** Cadance and Shining Armor thought Sonic and Twilight were going to have a relationship, but it gets shot down when the two in question point out they're just friends, and that's final.
* ShoutOut: [[ShoutOut/SonicGenerationsFriendshipIsTimeless There's a separate page for that.]]
** ReferenceOverdosed: Not to the point of, say, ''WebAnimation/DoubleRainboom'', since most of the {{Shout Out}}s are to Sonic works. There's still a lot of those, though.
* ShownTheirWork: [=GreenSonic21=] has clearly done plenty of research on not only pretty much all of the Sonic games, but also [[Anime/SonicX the]] {{WesternAnimation/Sonic|SatAM}} [[WesternAnimation/AdventuresOfSonicTheHedgehog cartoons]] and [[ComicBook/SonicTheComic comic]] [[ComicBook/SonicTheHedgehog books]], and it clearly shows. He's even referenced events from [[ComicBook/MyLittlePonyFriendshipIsMagicIDW the FiM comic books]] into the story.
* SpoilerTitle: {{Averted|Trope}}. Chapter 13 is listed with a ? in place of Trixie's name, hiding her presence in the chapter.
* TwitchyEye: When Spike pushes Amy's BerserkButton and leaves Sweet Apple Acres, one of Amy's eyes twitch as she follows the baby dragon.
* UnexpectedCharacter: Where did Babs come from?
** As a matter of fact, where did half of the ponies come from? They weren't with the rest in chapter 1.
* VillainHasAPoint: Eggman is an evil man, but his ReasonYouSuckSpeech to the Mane 6, Celestia, and Shining Armor about how they've treated Twilight as a tool, and have ignored her feelings is pretty dead on, especially since neither of them could really argue with it (and he brings up events from the fanfic itself where the characters do exactly that).
* WinsByDoingAbsolutelyNothing: The TropeNamer is referenced in chapter 7 of ''Adventures on the Friendship Express'':
--> '''Rarity:''' So we're all taking part in this?
--> '''Sonic:''' Seems that way. Unless you want to hope you'll win by doing absolutely nothing?
* YouAreNotAlone: Like in the original game, everybody ([[HoldYourHippogriffs and everypony]]) shows up to help Sonic and the Mane 6 during the final boss battle. And it's [[Main/LoadsAndLoadsOfCharacters more than twice the amount of characters than in the original game.]]
* YouMonster: Cadance says this to Dr. Eggman [[spoiler:after he crushes Sonic and the girls with the Time Eater.]]
